PATENT @rrrc BARREL-HEAD CUTTER.

SPECIFICATION forming part of Letters Patent No. 271,934, dated February 6,1883.

- Application filed September 2, 1882. (No model.)

ing had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 ofthe drawings is a sectional view of the barrel-head. Fig. 2 is a face view of the cutter. Fig. 3 is a vertical sectional view of the same, and Fig. 4 is a detail view. a

This inventlon relates to machines for turning barrel-heads. In a machine constructed for such purpose the barrel-head to be turned is usually held between two rotary face-plates, capable of being opened or closed, so as to admit of the head being placed between them or removed after it has been turned. To effect the adjustment of one of the face-plates, so as to admit of the said insertion or removal of the head, a treadle and appropriate connections are employed. The saw andknives for cutting or paring the head, so as to give it the required marginal bevels, are carried by a shaft or arbor, which is rotated independently of the shaft carrying the face-plates and arranged to be swung around, so as to bring the saw and knives into position for operating upon the wooden barrel-head which is held between the face-plates. The shaft carrying the face-plates is turned by suitable gearing, so that when the saw and knives or cutters are revolved and brought into action one revotion of the face-plates carrying the head will be sufficient to finish the latter. Heretofore in machinesof such character the concave saw has been employed for cutting the loweror broad bevel of the head while upon the knifeblock, which is securedagainst the concave face of the saw, two sets of cutters of two each have been employedone for cutting the upper or face bevel of the head and the small set for cutting the middle square edge between said two bevels. The objection to such arrangement is that the two knives or cutters do not cut the face-bevel as smooth as is desired. I

It is the object of my invention to obviate such defect, and to such end I provide between the cutter-block and the aforesaid concave saw a smaller intermediate saw for cutting the square edge between the two bevels. I employ four cutters upon the cutter-block, all adapted to cut or pare the edge of the barrel-head, so as to form the face-bevel of the same. These four knives perform the work more effectively than two, which latter number could only be used in machines heretofore constructed.

In the annexed drawings, A indicates a section of a barrel-head. a indicates the facebevel; a, the lower broad bevel, and a the intermediate square edge. B designates a large concavo-convex circular saw. I) is a small concaved circular saw fixed between the knife or cutter block 0 and the large saw B. The

block and saws are arranged upon the rotary shaft or arbor When applied to the machine and clamped together by means of a nut, E, whichis tightened up againstacollaror washer, F, located between the nut and the large saw. To the cutter-block are adjustably secured the four cutters, G, arranged in line and adapted to cut the face-bevel on the cask or barrel head. The cutters are slotted and held upon the sides of the block by means of bolts 9, passin g through their slots.

In operation the cutters pare or cut the head, so as to form the face-bevel a. The small intermediate saw forms the middle square edge and the large saw the under wide bevel. This is accomplished by swinging the shaft carry ing the rotary face-plates between which the material tobe operated upon isclamped around, so as to bring the edge of the blank at such an angle with relation to the saws and the cutters that both of the saws and the cutters will operate nearly at the same time, the smaller saw being the last to operate to cut the square edgea of the barrel-head after the two bevels have been formed.

Having thus described my invention, what I claim is- 1. In a device for turning barrel-heads, the small concave circular saw arranged between the large circular saw and the cutter-block, adapted to form the face-bevel of the said barro said smaller saw being adapted to cut the midrel-head, substantially as described.
